A major objective in the field of heavy ion collisions is to quantify and characterize the properties of QGP by studying heavy flavor production. The $J/\psi$ meson can be produced in one of three ways: 1) directly in the collision, 2) indirectly via feeddown from heavier charmonium states, or 3) from the decay of B mesons. If the $J/\psi$ is produced through either of the first two methods, it is called a prompt $J/\psi$, while the third method produces a non-prompt $J/\psi$. With the newly commissioned forward silicon vertex detector (FVTX) in 2012, it is possible for the first time at the PHENIX experiment to extract non-prompt $J/\psi$'s from the inclusive $J/\psi$ signal by measuring a displaced vertex. In this poster, we will present the current status of the data analysis for $J/\psi$'s that come from B decays in pp collisions at $\sqrt{s_{_{NN}}}=510$ GeV with the PHENIX experiment at RHIC. Results of this analysis will provide a proof-of-principle for future measurement in heavy ion collisions.
